Answer 1

Your NullPointer Exception is in getCount() line 27:

Caused by: java.lang.NullPointerException
at com.droidnova.android.howto.optionmenu.LazyAdapter.getCount(LazyAdapter.java:27)

You could fix the sympton by changing getCount() to:

public int getCount() {
    if(data != null){
        return data.length;
    }
    return 0;
}
